Four options for the communication channel model are offered in DFTS2 experiments: perfect channel (no loss), independent and identically distributed (iid) random loss, Gilbert-Elliott (GE) channel [1]}, and user-provided packet traces. The GE model, also known as the burst loss model, has been shown to adequately capture observed packet loss patterns over the Internet [1]}, [3]}. This motivates our choice of GE channel models for our experiments. This packet loss model is a two-state Markov model with a good \((G)\)  and a bad \((B)\)  state. It can be parameterized by the burst loss probability \(P_B\)  and the average burst length \(L_B\) . The conversion from \(P_B\)  and \(L_B\)  to the four state transition probabilities is as follows:
\(\begin{alignedat}{2}p_{B\rightarrow G} & = \frac{1}{L_B}, \quad && p_{G\rightarrow B} = \frac{P_B}{L_B(1-P_B)},\\p_{B\rightarrow B} & =1-p_{B\rightarrow G}, \quad && p_{G\rightarrow G} = 1-p_{G\rightarrow B}.\end{alignedat}\)
